A simple circuit of a crystal oscillator and its application to a high-resolution NMR spectrometer

Describes a simple circuit of a crystal oscillator operating at frequencies from several megahertz to a hundred megahertz with a frequency stability of one part to 10
⁸
constructed using a dual gate MOSFET. This RF transmitter accompanied by an RF-tuned receiver can be used as a high-resolution NMR spectrometer and as a precise Gaussmeter.
